METALLIC PACKING-RING FOR PISTONS, PUMP -BUCKETS, 89C.

. SPECIFICATION forming part of Letters Patent No. 313,980, dated March 17, 1885.

Application filed December 12, 1884. (No model.) Patented in England May 27, 1884, No. 8,264.

, To all whom it may concern:

Be it known that I, WILLIAM BUOKLEY, a subject of the Queen of Great Britain, residing at Sheffield, in the county of York, England, engineer, have invented certain new and useful Improvements in Metallic Packing- Rings for Pistons, Pump-Buckets, Valves, and for other Similar Purposes, (for which I have received Letters Patent in Great Britain, no; 8,264, dated May 27, 1884,) of which the following is a specification.

This invention relates to certain new and useful improvements in the manufacture or construction of rings for pistons, pump-buckets, valves, or for other similar purposes, its object being the production of metallic packing-rings that will be more durable and accurate in Working and more efficient where high or low pressure steam or air, water, or other motive power is used than the packing-rings hitherto used.

According to one method of carrying out my invention in practice, I make a packingring the whole breadth (or nearly so) of the distance between the flanges of the piston, (for eXample,) instead ofniaking and using two or more rings, as generally adopted. On one edge of this ring, on its inner side, there is a flange or inner ring, the inner surface of which flange or inner ring may be either of a parallel, angular, circular, curved, or of any other desired and suitable form. The flange or inner ring can be made as part of the broad ring; or it may be made separately, if preferred, and attached to it by means of pins or screws, or in any other suitableway. A loose flange or inner ring similar to the above can be placed at the other edge of the ring. The packing-rings, being made in one breadth instead of in two or more breadths, as generally used, are much stronger, will keep in'a parallel position-while working, they do not cant or twist, and they will act effectively in all cases where either high or low pressure motive power is used. These packing-rings can be made of either cast, wrought, or malleable iron, steel, brass, or of any other suitable metallic material, and the flanges or inner rings may be fitted to the broad ring in any desirable and convenient way by parallel shouldered, beveled, or circular or curved surfaces.

Figure 1 on the accompanying drawings represents a plan, and Fig. 2 a sectional elevation, of a broad ring, a, having an inclined or beveled flange, b, on the inside at one edge.

At the other edge, on the inside. is a loose ring, 0, also having an inclined or beveled edge. Fig. 3 shows a section of a broad ring with a parallel flange at one edge, d, and at the other edge a loose parallel ring, 6. Fig. 4 shows in section a similar broad ring with a loose beveled ring, f, at one edge. Fig. 5 shows in section a broad ring with a beveled flange, p, on the inside at one edge, and an inner flanged ring, g, at the other side. Fig. 6 shows a section of a broad ring with a parallel flange at one edge, 7', and with an inner ring with a parallel flange at the edge 8. Fig. 7 shows in section a broad ring with a beveled flange, t, at one edge, the other edge, a, being made thicker, forming a bearing for the inner loose ring. Figs. 8 and 9 show in section broad rings with beveled flanges on the inside at one edge, e, and beveled at the other edges to fit the inner beveled rings, to. Fig. 10 shows in section a broad ring, :v, with a beveled flange, y, on the inside at one edge, with a loose beveled ring with a flange, a, at the other edge. broad ring with a flange, 1, at one edge partly beveled and partly parallel, with a similarlyshaped loose flange, 2, at the other edge. Fig. 12 shows in section a broad ring with flange having an inner circular or curved surface, 3, at one edge, and an inner ring with a circular or curved surface, 4, at the other edge. Fig. 13 shows in section a broad ring with an inner flange or rib, 5, at a distance from the edge, with an inner loose ring, 6, at a distance from the other edge. Fig. 14 shows in section a broad ring with a beveled flange, 7, on the inside at one edge.

Having described and ascertained the nature of the said invention and the manner of performing the same, what I claim is- The improved ring for pistons, pumps, valves, and for other similar purposes, the same being constructed of an outer broad ring Fig. 11 shows in section a body with an inner flange at one edge and a loose ring at the other edge, substantially as hereinbet'ore described and illustrated.
